Mail plugin not working

[crazystick]

There seem to be two plugins here, but only the GCS plaugin is referenced in the tutorial

I need to get mail working and so I tried installing the appengine-plugin but it can't be activated - fails with the error

Warning: require_once(google/appengine/api/urlfetch_service_pb.php): failed to open stream: No such file or directory in /srv/wp-content/plugins/google-app-engine/modules/urlfetch.php on line 72 Fatal error: require_once(): Failed opening required 'google/appengine/api/urlfetch_service_pb.php' (include_path='.:/usr/lib/php') in /srv/wp-content/plugins/google-app-engine/modules/urlfetch.php on line 72

It looks like the appengine-plugin includes an obsolete version of GCS upload functionality so I guess they will conflict also.

Is there a way to get mail functionality today?
